Abstract

PROBLEM TO BE SOLVED: To easily store and transport foods by a method wherein four corners of a square ground paper with a mark showing cutting positions of a formed food are cut off and the paper is formed, with its film facing inward, into a prism shape so that the paper can be easily formed into a prism shape and after forming a food, the side of the prism-shaped body is turned down to facilitate cutting of the food. SOLUTION: A synthetic resin film 1 is bonded to the surface of a ground paper 1 and four corners are cut off so as to form a square notch at each corner. On the surface of the paper 1, there are straight lines and figures, as marks, to show cutting positions, which can be seen through the film 2. When the side edges 3 of the paper 1 are folded up to form a prism-shaped body, the film 2 only extrudes outward from the corner to form an excessive part 4. The part 4 is properly folded and the body is put into a mold having nearly the same shape as the body, and a food having shape retaining property is poured into the body and cooled to form the food, following which the body, i.e., a container, is taken out of the mold and the edges 3 are turned down using the parts 4. The food is cut to a required number of pieces along the lines of marks showing cutting positions of the edges 3 using a kitchen knife.

Description of the Related Art Conventionally, foods such as agar and gelatin which are heated and melted, poured into a mold, cooled and solidified, and cut into a desired shape are manufactured by using a wooden box and a stainless steel frame assembled in a rectangular parallelepiped. . When manufactured in large quantities for commercial use, a synthetic resin container having four corners at right angles and no taper is generally used by an injection molding method. In addition, there is a case where a water-tight composite container made of a synthetic resin film bonded to the inside of the paper is assembled, but in the case of the tray-shaped container 11 as shown in FIG. 6C, (a) From (b)
As shown in Fig. 4, the four corners corresponding to the contact points of the wall are folded inward along a diagonal line aa ', and the folding portion 12 is used by being bonded to either outside of the four walls, so that the container is pre-bonded and assembled. . When a rectangular parallelepiped container is required, the wall surface cannot be tapered, so that it cannot be stacked during storage or transportation.

A food container, characterized in that a mount having only four corners cut off is assembled into a rectangular parallelepiped with the film side as an inner surface. The easy peelability of the easily peelable film means that the food that has been cast and shaped can be easily taken out, and materials for the film include synthetic resin films and aluminum foils.

The present invention is also a method for producing a packaged food, characterized in that the food container is placed in a mold of substantially the same shape, and a shape-retaining food is poured and molded. Before pouring a shape-retaining food, characters or a pattern may be printed in advance at a desired position on the inner surface of the container, and this may be transferred to a shaped food. According to the manufacturing method of the present invention, the film protruding from the four corners may be packaged by placing the container in a mold having substantially the same shape without adhering and fixing it to the side faces. In this case, the protruding film portion is not particularly disturbing because the film is thin.

Use polyvinylidene chloride as appropriate depending on the intended food. When it is necessary to use a microwave oven, aluminum foil may be used. The mark indicating the cutting position may be displayed on the surface of the mount when the film is a transparent resin, and is displayed on the surface of the opaque film when the film is opaque such as aluminum foil. Foods that are subject to casting and shaping are mainly those that use agar and gelatin.

ることができる。In the container of the present invention, the film portions protruding at the four corners are not particularly troublesome when the container is loaded in a mold of substantially the same shape without being fixed to the side surfaces. Therefore, if the food material is poured and shaped while the container is kept in the mold, and if it is taken out from the mold as it is, the side wall of the container keeps a tray shape due to the adhesive force with the food, but the side surface sticks out the protruding film part. It can be defeated if necessary as a clue. When the side surface is tilted, a mark indicating the cutting position appears, and it is possible to cut into a desired size along the mark. If the size to be cut is known in advance, the viscous foods such as agar, gelatin, egg yolk, and starch are kneaded with edible pigments, caramel, etc. on the film surface of each corresponding position by screen printing method etc. With the coloring that was made intricately, Kotobuki, pine, bamboo, plum,
Draw small patterns and patterns such as waves and paper cranes, and pour food ingredients into them. After cooling, the food can be cut and turned inside out to create visually appealing foods such as condolences and seasonal kaiseki dishes.

所要個数に切り分ける。Embodiments will be described with reference to the drawings. FIG. 1 is a development view of an embodiment of the container of the present invention. Reference numeral 1 is a mount, on the surface of which a synthetic resin film 2 is attached. The four corners of the mount 1 are cut off into squares. A straight line and a number are shown on the surface of the mount 1 as a mark indicating a cutting position. This mark can be seen through the synthetic resin film 2. For example, if you cut on the straight line at the position of number 3, it will be divided into 3 pieces, and 3
If you divide them at the same time on the line of the numbers of 4 and 3, it will be 3 ×
It can be divided into 4 = 12 pieces. FIG. 2 is a perspective view in which the side surface 3 is folded up to form a rectangular parallelepiped. At this time, only the film protrudes into the extra portions 4 at the four corners. The extra portion 4 is appropriately folded and placed in a mold 5 having substantially the same shape as shown in FIG. In FIG. 4, after shaping, the container is taken out of the mold 5 and the side surface 3 is tilted outward with the extra portion 4 etc. as a clue. Since a mark indicating the cutting position is displayed on the side surface 3 as shown in FIG. 5, the kitchen knife 7 is cut along the line to divide the food 6 into the required number.

ことができる。The packaging container of the present invention is easy to assemble into a rectangular parallelepiped, and the side surface can be easily laid down after shaping the food, so that not only the cutting operation of the food can be facilitated but also the cutting position is displayed. According to the mark, the food can be accurately cut into a desired number. In addition, since it is usually a flat plate, it is possible to stack many kinds as it is, which is convenient for storage and transportation. Further, in the manufacturing method, if an auxiliary mold is used, the container can be easily assembled and can be easily removed from the mold together with the shaped food, so that the packaged food can be manufactured efficiently.
